To all in am it may concern: 1

Be it known that I, W. BRITTON LAnn, a citizen or the United States, anda resident of Evanston, in the county of Cook and State of Illinois,'have invented a certain new and useful Improvement in Cushioning Meansfor Railway-Cars, of which the following is a description, referencebeing had to the accompanying drawing, which formsapart of myspecification. v t

My invention relates more particularly to means whereby a pneumaticcushion will be provided for railways'cars, the means being soconstructed that the elastic medium or 18 air may be supplied by theusual air line of the train.

The object of the invention is the provision of means whereby an easierriding car is produced, which will be practically free of the shocks andvibration encountered where the usual truck springs alone are employed;and whereby the lateral swaying of the car due to unevenness in the roadbed will be practically eliminated through the 5 absorption of themotion by the cushioning means mounted on opposite sides of the car.thereby also greatly relieving the rails and ties from the shocks andstresses to which v they are subjected with the present existing 0constructions.

In the drawings :.-Figure 1 is a cross secconnection with the type oftruck and car bod at present in use.

The invention consists in providing one ormore cylinders 10 at both,sides of the car ody at points coincident with the trucks. so The sidewalls of the cylinders may be provided with the flanges 11, 11, whichare" adapted to extend beneath the adjacentlongitudinal sills 5 andsecured thereto in any suitable manner as illustrated for example inFig. 1. The cylinder 10 is preferably provided at a suitable pointintermediate of its ends with an escape port or opening 12, see Fig. 2,while the side of the cylinder facing lengthwise of the car ispreferablyvo provided with a valve chamber 13, which is connected withthe conduit or pipe 14 which connects with the usual air line of thecar. The valve chamber has communication with the cylinder interiorrough the port 15. The chamber 13 is provided with a suitable slidingvalve as shown at 16 adapted to move in a vertical direction therein.

Cylinder 10, which is shown with its lower end open, is provided with asuitable piston 17. The piston 1'1 is adapted to be secured to or reston the ends of the car bolster 7 as shown in Fig. 1. The piston 17 ispro vided with suitable packing rings or glands 18 so as to provide anair tight sliding con- 35 tion.

Fig. 3 is a horizontal sectional view taken on the line 3-3 ofFig. 2. Fig. 4 is a detail view showing 49 the valve mechanism inperspective.

In the drawing and Fig. 1, 5 represents the usual longitudinal sills ofthe car arranged beneath the floor 6,, with my improved cushioning meansshown a plied be- 5 tween the two longitudinal side SlllS of the car atopposite sides thereof; the device being preferably arrangedintermediate of the longitudinal sills of the car and the car bolster 7,which latter is mounted above the 59 truck bolster 8, with the usualcenter bear- 111 9 arranged between the two bolsters.

As my invention does not relate to the description of the trukwill not.be entered as the inventipnis adapted foruse in construction of thetruck or car," a specific of Fig. 1 looking inthat valve 16 chamber 13until air has entered cylinder 10 I and forced the piston.

nection between the piston and the walls of the cylinders. The piston 17is provided with an extension or lug 19 which has a suitable opening toreceive the stem 20 of valve 16. In the drawing, this stem 20 is .shownscrew threaded to receive nuts 21, whereby therelation between thepiston and the valve may be controlled:

In the application of my invention, one

or more cylinders are arranged between the longitudinal sills of the carbody at points preferably above the ends of the car bolster; thecylinders being secured to the longitudinal sills as previously'described, while the pistons are placed on the ends of the car bolster,and if desired, may be secured thereto. The valve chamber 13 is thenconnected with the air line of the train by means of pipe 14, so 13 andbe. allowed to pass into cylinder 10, which is made possible by reas'on'of the fact will be in the upper'part ofconstruction shown in the 90that air may flow into chamber "With the valve 16 in the pe the liftingor upward inevei'nent of the plligu 2, it is evident h ew )L pesil'eside of the car will close off the flow cylinder Wlll he she 01' 111" tothe cylinders at that side of lhe inders 10 are filled wit f1; it is car-which above the norm all level so that '1 5 that iihe pistons 17 willhe i eeced i 21 substantially uniform depth 01 air cushion 79 cylinduntil they in Contact will be iniiiniained. upper or end Well of thecylindew The l -xpuse 23 will permit the air to seep the pistons movedup inte this 0 1" I or pas hack into the air line 01"" the 'i'lfllllwill be seen that the Valve 16 Wlli b CODA-- and thus prevent itseecape, all the same time w pelled to move upward in valve chamber "Lrelieving the pressure in the cylinders clur- 7:5
